Description of the Related Art There are two methods for preventing corrosion of a rail: a method of making the material of the rail a component having excellent corrosion resistance, and a method of applying a surface treatment such as painting, thermal spray coating, and rubber lining to the rail.
However, in the method of changing the rail material, Cu,
Even if alloying elements such as Cr, Ni, and Mo are added, if the total of these added elements is less than 10%, little effect is seen in the wet environment of the tunnel. On the other hand, the addition of 10% or more has the disadvantage that the cost becomes extremely high. on the other hand,
In the case of surface treatment such as painting or coating, corrosion protection of the area covered with the coating film or coating layer is sufficient, but the corrosion medium such as water penetrates from the bare / painting or bare / coating boundary and the coating film. Alternatively, the edge of the coating layer is deteriorated.

ある。SUMMARY OF THE INVENTION The gist of the present invention is to paint or coat the entire surface of the rail except for the top and side wheel contact portions of the rail and to define the bare / painted or bare / covered boundaries. An anticorrosion rail with an angle between the end of the coating or coating layer and the side of the head of 45 degrees or less.
Alternatively, the anticorrosion rail is formed by forming a coating or coating layer on the entire surface below the rail jaw and forming a coating or coating layer, and forming an edge of the coating or coating layer with a side surface of the rail head so as to have a vertical lower shape.

同様の角度となるようにする。[0006] The present invention stipulates that the coating or coating is applied particularly to the head side of the wheel non-contact portion for the following reasons. That is, according to the present invention, after a coating film or a coating layer is formed on the rail surface, as shown in FIG. 1 (a), an angle θ 1 between the ends of the rail and the head side surface is 45 degrees using a spatula or a grinder or the like. Processing is performed so as to have the following acute angle, or in the case of rubber or the like, processing is performed on the end portion in advance so that the same angle is obtained.

ることにより、さらなる寿命延長ができる利点がある。When the angle θ 2 between the end of the coating or coating layer having a constant thickness and the head side is about 90 degrees as shown in FIG. 2, this processing is performed over the entire length of the rail. Prevention of swelling and peeling of the coating film or the end of the coating layer at an early stage is caused by accumulating water and accelerating corrosion by being constantly in contact with the corrosive medium. Further, if blistering or peeling occurs at the end of the coating film or the coating layer after a certain number of years, there is an advantage that the life can be further extended by removing the deteriorated portion with a grinder or the like.

を防止してレールの寿命延長を図ることができる。When coating or coating is applied to the entire surface of the rail below the rail jaw as shown in FIG. 1 (b), the coating or coating layer is processed so that the end of the coating or coating layer is perpendicular to the rail head side surface. This also has the effect of preventing stagnation of water, and prevents blistering and peeling of the coating film or the end portion of the coating layer at an early stage, thereby extending the life of the rail.

寿命を著しく延長できる。According to the present invention as described above, it is possible to prevent the occurrence of swelling and peeling due to the stagnation of a corrosive medium such as water at the end of a coating film or a coating layer, which has been frequently seen so far. Also, the service life of the surface-treated rail can be remarkably prolonged even in a leaky undersea tunnel.
